But with the memory of a deep recession still lingering, businesses and consumers remained cautious about both investing and spending. While business fundamentals showed signs of improvement, there was still a reluctance to hire, and high unemployment remains a problem. Wary investors, concerned about risk, gravitated towards cash and bonds, until a rally late in the year lifted equity returns. We remain generally optimistic about the prospects for economic recovery, although it may occur more slowly than many would like. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. This strategy has generally performed well for many investors. Bond markets certainly rewarded investors in the first eleven months of 2010. While the equity markets barely budged for those first eleven months, valuations were inexpensive relative to bonds, compared with historic levels, and represented potentially good value for long-term investors, many of whom were rewarded in the subsequent late-year equity rally. Pioneer has not changed the basic approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. Our experienced professionals devote themselves to the careful research needed to identify investment opportunities in markets around the world. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Real Estate Shares | Annual Report | 12/31/10 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. We greatly appreciate your trust in us and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Real Estate Shares | Annual Report | 12/31/10 3 Portfolio Management Discussion | 12/31/10 U.S. real estate investment trusts (REITs) continued their impressive performance run during the 12 months ended December 31, 2010, posting rewarding gains for the second year in a row. Broader equity market gains, combined with ongoing signs of stabilization in commercial real estate market fundamentals, a low-interest-rate environment, and demand for higher-yielding securities helped to drive REITs higher during the 12-month reporting period. In the following interview, Matthew Troxell of AEW Capital Management, L.P., Pioneer Real Estate Shares' sub-adviser, discusses the REIT market and the Fund's performance over the 12-month period. Q How did the Fund perform over the 12 months ended December 31, 2010? A For the 12 months ended December 31, 2010, Pioneer Real Estate Shares Fund Class A shares returned 28.25% at net asset value, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI) U.S. REIT Index1 returned 28.48%. Over the same period, the average return of the 224 mutual funds in Lipper's Real Estate Funds category was 27.60%. The Fund performed essentially in line with its benchmark during the period. Positive stock selection and sector allocation strategies contributed to strong absolute results for the Fund overall. Stock selection in the office, storage, and hotel sectors was especially rewarding, but those gains were tempered by disappointing results in the shopping center and regional mall sectors. The Fund's sector allocation results benefited from an emphasis on the outperforming apartment sector and limited exposure to the underperforming health care sector. Q What investments influenced the Fund's performance favorably over the 12 months ended December 31, 2010? A With its high-quality asset portfolio and well-managed development pipeline, Extra Space Storage enjoyed solid operating results and a stable balance sheet. A recovery in business travel and improving fundamentals in the lodging industry translated into a strong year for the stock of Starwoods Hotels & Resorts Worldwide. The company's competitive international presence, high-quality portfolio, and upscale focus have been important drivers of growth. Our decision to overweight the Fund to both of these top-performing holdings proved rewarding during the 12-month period. 4 Pioneer Real Estate Shares | Annual Report | 12/31/10 Q Which Fund investments proved most disappointing over the 12 months ended December 31, 2010? A Our decision to overweight the Fund to investments in the underperforming Pebblebrook Hotel Trust and Nationwide Health Properties was disappointing. Pebblebrook lagged its hotel peers during the 12-month period due to the fact that the company had not deployed the majority of the cash raised from its late 2009 initial public offering in the first half of 2010. The company subsequently announced several acquisitions as the calendar year progressed. We remain committed to the stock, as we believe the company continues to represent an attractive relative value in the hotel sector, especially considering a healthy balance sheet that has management well positioned to acquire high-quality assets going forward. National Health Property's underperformance was driven primarily by its announcement of lower-than-anticipated funds from operations guidance for 2010. Furthermore, through an equity share issuance to help strengthen its balance sheet, management actually issued more shares than expected, but we did not view that as negatively as the market did. Q How did you adjust the Fund's investment strategy over the 12 months ended December 31, 2010, in light of improving market conditions? A Our strategy has not changed. We continue to construct the Fund's portfolio through our bottom-up, value-oriented investment process, which attempts to find mispriced securities relative to their peers within each property sector. Decisions to overweight or underweight different individual stocks depend upon our view of market conditions and company-specific variables. Q Given the U.S. economy's uneven recovery, how have the various property types in which the Fund is invested been faring? A There are two sides to the question: the fundamentals of the property markets, and the degree to which the expected improvement in fundamentals has already been priced into the market. Regarding property market fundamentals, the lodging and apartment sectors have made the most progress since the markets troughed in March 2009. In particular, in the apartment sector, vacancy rates are not far above their long-term averages, and rents are growing, though they remain substantially below peak levels in many markets. Self-storage fundamentals have also been very strong, as they are driven by many of the same factors as the apartment sector. The recovery in the retail, office and industrial sectors is at a much earlier stage, with vacancy rates still close to peak levels, although improving. The longer lease structure in those sectors has the effect of lengthening the time until net operating incomes begin to improve. For the next year or two, many leases in the sectors will be rolling down to lower market rents, and Pioneer Real Estate Shares | Annual Report | 12/31/10 5 that is likely to continue for some time, even after market rents have begun to rise. This is particularly true in the office and retail sectors due to their longer leases. With all that said, we think retail, office and industrial net income levels have bottomed. REIT fundamentals in health care have been the most resilient through the downturn, given the sector's lower leverage levels and lower sensitivity to gyrations in the general economy. Q Do you think the positive momentum that we saw in real estate markets over the 12 months ended December 31, 2010, will continue into 2011? A The continuing improvement in commercial real estate fundamentals in 2010 suggests that values should continue to recover, all other things being equal. We think demand, particularly for storage space, is gathering momentum, and new construction supply in apartments is likely to remain very limited for the foreseeable future, which should bring down vacancy rates during 2011 and support improvements in rents. Accordingly, we have overweighted the Fund to the self-storage and apartment sectors, which offer the best relative value in our opinion. The Fund is substantially underweight health care, which has been trading at extremely high premiums to underlying property net asset values. REITs have been very conservative about raising dividends over the past couple of years, and with income nearing or past troughs and payout ratios below long-term norms, we expect to see dividends increase this year and beyond. Investors continue to look for yield in a world of few alternatives, and we believe REITs offer one of the primary investment alternatives. With the risk of deflation receding in recent months, the property portfolios held by REITs are a real asset that, should inflation re-emerge, offer some inflation protection relative to pure fixed-income instruments. 1 The MSCI information may only be used for your internal use, may not be reproduced or re-disseminated in any form and may not be used as a basis for or a component of any financial instruments or products or indices.

Pioneer Real Estate Shares | Annual Report | 12/31/10 13 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period.

The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

The accompanying notes are an integral part of these financial statements. 28 Pioneer Real Estate Shares | Annual Report | 12/31/10 Notes to Financial Statements | 12/31/10 1. Organization and Significant Accounting Policies Pioneer Real Estate Shares (the Fund) is a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to seek long-term growth of capital. Current income is a secondary objective. The Fund offers four classes of shares designated as Class A, Class B, Class C and Class Y shares. Effective as of the close of business on December 31, 2009, Class B shares are no longer offered to new or existing shareholders, except that dividends and/or capital gain distributions may continue to be reinvested in Class B shares, and shareholders may exchange their Class B shares for Class B shares of other Pioneer funds, as permitted by existing exchange privileges. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. Because the Fund may invest a substantial portion of its assets in Real Estate Investment Trusts (REITs), the Fund may be subject to certain risks associated with direct investments in REITs. REITs may be affected by changes in the value of their underlying properties and by defaults of their borrowers or tenants. REITs depend generally on their ability to generate cash flow to make distributions to shareowners, and certain REITs have self-liquidation provisions by which mortgages held may be paid in full and distributions of capital returns may be made at any time. In addition, the performance of a REIT may be affected by its failure to qualify for tax-free pass through of income under the Internal Revenue Code or its failure to maintain exemption from registration under the Investment Company Act of 1940. The Fund's Pioneer Real Estate Shares | Annual Report | 12/31/10 29 prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued at the mean between the last bid and asked prices. Securities for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At December 31, 2010, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. 30 Pioneer Real Estate Shares | Annual Report | 12/31/10 Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. A portion of the dividend income recorded by the Fund is from distributions by publicly traded REITs, and such distributions for tax purposes may also consist of capital gains and return of capital. The actual return of capital and capital gains portions of such distributions will be determined by formal notifications from the REITs subsequent to the calendar year-end. Distributions received from the REITs that are determined to be a return of capital are recorded by the Fund as a reduction of the cost basis of the securities held and those determined to be capital gain are reflected as such on the Statement of Operations. At December 31, 2010, the Fund had a net capital loss carryforward of $27,852,362 of which the following amounts will expire between 2016 and 2018 if not utilized: $7,060,199 in 2016, $20,315,492 in 2017 and $476,671 in 2018. The Fund has elected to defer approximately $675,156 of capital losses recognized between November 1, 2010 and December 31, 2010 to its fiscal year ending December 31, 2011. Pioneer Real Estate Shares | Annual Report | 12/31/10 31 The tax character of distributions paid during the years ended December 31, 2010 and December 31, 2009 was as follows: ----------------------------------------------------------------------------- 2010 2009 ----------------------------------------------------------------------------- Distributions paid from: Ordinary income $1,688,813 $2,739,314 Tax return of capital 1,253,410 1,105,994 ----------------------------------------------------------------------------- Total $2,942,223 $3,845,308 ============================================================================= The following shows the components of distributable earnings on a federal income tax basis at December 31, 2010: ----------------------------------------------------------------------------- 2010 ----------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(27,852,362) Post-October loss deferred (675,156) Unrealized appreciation 57,187,303 ----------------------------------------------------------------------------- Total $ 28,659,785 ============================================================================= The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $14,034 in underwriting commissions on the sale of Class A shares during the year ended December 31, 2010. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment 32 Pioneer Real Estate Shares | Annual Report | 12/31/10 income dividends to Class A, Class B, Class C and Class Y shares can reflect different transfer agent and distribution expense rates. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. F. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.80% of the Fund's average daily net assets up to $1 billion; and 0.75% of the Fund's average daily net assets over $1 billion. Prior to January 1, 2010, management fees were calculated daily at the annual rate of 0.80% of the Fund's average daily net assets. PIM pays a portion of the fee it receives from the Fund to AEW Pioneer Real Estate Shares | Annual Report | 12/31/10 33 Capital Management, L.P. as compensation for sub-advisory services to the Fund. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $3,941 in management fees, administrative costs and certain other reimbursements payable to PIM at December 31, 2010. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended December 31, 2010, such out-of-pocket expenses by class of shares were as follows: - -------------------------------------------------------------------------------- Shareholder Communications: - -------------------------------------------------------------------------------- Class A $ 84,076 Class B 24,216 Class C 11,121 Class Y 1,185 - -------------------------------------------------------------------------------- Total $120,598 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $45,939 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at December 31, 2010. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,131 in distribution fees payable to PFD at December 31, 2010. 34 Pioneer Real Estate Shares | Annual Report | 12/31/10 In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase (within 12 months for purchases made on or after April 1, 2009). Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended December 31, 2010, CDSCs in the amount of $10,072 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended December 31, 2010, the Fund's expenses were not reduced under such arrangements. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a $165 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on borrowings is payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended December 31, 2010, the Fund had no borrowings under this agreement. 7. Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements. Pioneer Real Estate Shares | Annual Report | 12/31/10 35 Report of Independent Registered Public Accounting Firm To the Board of Trustees and Shareowners of Pioneer Real Estate Shares: - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Real Estate Shares (the "Fund") as of December 31, 2010, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2010, by correspondence with the custodian and broker or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Real Estate Shares at December 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. Ernst & Young LLP Boston, Massachusetts February 25, 2011 36 Pioneer Real Estate Shares | Annual Report | 12/31/10 Approval of Investment Advisory and Sub-Advisory Agreements Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Real Estate Shares (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. PIM has retained AEW Capital Management, L.P. (AEW) to serve as the sub-adviser to the Fund pursuant to a sub-advisory agreement between PIM and the sub-adviser. In order for PIM and AEW to remain the investment adviser and sub-adviser of the Fund, respectively, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement and the sub-advisory agreement for the Fund. The contract review process began in March 2010 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2010, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement and the sub-advisory agreement. The contract review materials were provided to the Trustees in September 2010. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the independent Trustees of the Fund were held in July, September, October, and November, 2010 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at each regularly scheduled meeting. At a meeting held on November 16, 2010, based on their evaluation of the information provided by PIM, the sub-adviser and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement and the sub-advisory agreement for another year. In considering the renewal of the investment advisory agreement and the sub-advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreements. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM and the sub-adviser to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement and the sub-advisory agreement. The Trustees also reviewed the sub-adviser's investment approach for the Fund, its research process and its process for trade execution. The Trustees considered the resources of PIM and the sub-adviser and the personnel of PIM and the Pioneer Real Estate Shares | Annual Report | 12/31/10 37 sub-adviser who provide investment management services to the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. In addition, the Trustees considered the arrangements put in place to retain key investment and other personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers (including the sub-adviser) and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM and the sub-adviser to the Fund were satisfactory and consistent with the terms of the investment advisory agreement and the sub-advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the second quintile of its Morningstar category for the one, five and ten year periods ended June 30, 2010, and in the third quintile of its Morningstar category for the three year period ended June 30, 2010. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Trust Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees also considered that PIM, not the Fund, paid the sub-adviser pursuant to the sub-advisory agreement. The Trustees evaluated both the fee under the 38 Pioneer Real Estate Shares | Annual Report | 12/31/10 sub-advisory agreement and the portion of the fee under the investment advisory agreement retained by PIM. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2010 was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoint in the management fee schedule and the reduced fee rate on assets over $1 billion. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2010 was in the fifth quintile relative to its Strategic Insight peer group for the comparable period. The Trustees also considered the impact of the Fund's transfer agency and other non-management fee expenses on the Fund's expense ratio. The Trustees also reviewed management fees charged by PIM to its institutional and other clients. In evaluating the fees associated with PIM's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that in some instances the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also reviewed management fees charged by the sub- adviser to its other clients. The Trustees noted that in most instances the fee rates for those clients were higher than the sub-advisory fees paid to the sub- adviser with respect to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM, as well as the fees payable by PIM to the sub- adviser of the Fund, were reasonable in relation to the nature and quality of the services provided by PIM and the sub-adviser. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. The Trustees further considered the sub-advisory fees received by the sub-adviser with respect to the Fund and the percentage that such fees represented of the sub-adviser's overall revenues (for the 12-month period ended December 31, 2009). They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. Pioneer Real Estate Shares | Annual Report | 12/31/10 39 The Trustees concluded that the profit margins with respect to the management of the Fund were not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees recognize that economies of scale are difficult to identify and quantify and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Funds. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Funds. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits to each of PIM and the sub-adviser from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees also considered the benefits to the Fund and to the sub-adviser and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees considered the intangible benefits to each of PIM and the sub-adviser by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between each of PIM and the sub-adviser and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that each of the investment advisory agreement between PIM and the Fund and the sub-advisory agreement between PIM and the sub-adviser, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of each of the investment advisory agreement and the sub-advisory agreement for the Fund. 40 Pioneer Real Estate Shares | Annual Report | 12/31/10 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
